Fuzzy Cubic Spline Interpolation with Triangular Fuzzy Numbers

International Journal of Recent Technology and Engineering (IJRTE), 2020
In applied mathematics, the salient and engrossing aspect is how to best approximate a function in a given space. In this paper a cubic spline polynomial approximation as best approximations of fuzzy function on a discrete set of points. In this work a novel approach is adopted to show this method using Triangular fuzzy numbers.

Solving Fuzzy LR Interval Linear Systems using Nonlinear Programming

Fuzzy Optimization and Modeling
In this paper‎,‏‎ we use the least squares method to solve LR fuzzy interval systems by transforming an interval fuzzy number into two triangular fuzzy numbers. Then, ‎w‎e reduce the distance between the two obtained triangular fuzzy numbers to solve the

Fuzzy Unconstrained Optimization Problems with Triangular Fuzzy Numbers

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In this paper, we consider an unconstrained optimization problem with fuzzy valued functions. Using generalized Hukuhara differentiability of fuzzy functions in Newton’s method, we obtain an optimal solution of fuzzy unconstrained optimization problem without transforming to crisp equivalent form. Numerical examples are provided

An Extended MABAC Method Based on Triangular Fuzzy Neutrosophic Numbers for Multiple-Criteria Group Decision Making Problems

Axioms, 2020
In this manuscript, we extend the traditional multi-attributive border approximation area comparison (MABAC) method for the multiple-criteria group decision-making (MCGDM) with triangular fuzzy neutrosophic numbers (TFNNs) to propose the TFNNs-MABAC ...

On the ratio of fuzzy numbers – exact membership function computation and applications to decision making

Technological and Economic Development of Economy, 2015
In the present paper, we propose a new approach to solving the full fuzzy linear fractional programming problem. By this approach, we provide a tool for making good decisions in certain problems in which the goals may be modelled by linear fractional ...

Elementary operations on Gaussian fuzzy numbers for predictive modeling

Complex & Intelligent Systems
Elementary operations with fuzzy numbers are essential for implementing predictive fuzzy modeling. Although operations with triangular fuzzy numbers are well-established, they are not adequately studied for predictive modeling with Gaussian fuzzy numbers,
